Gain standards for accurate antenna measurements are expensive due to their extensive calibration procedure. This paper presents a concept for low cost antennas that comprise of sheets of FR-4 which are accurately manufactured using modern CNC technology. This accuracy in turn will render the calibration procedures unnecessary. The impact of tolerances is studied to determine whether the concept is eligible for further investigation.
